The “Valley Economy” Model of Regional Development: A Case Study of Mountain Areas in Beijing, Northern China

A case study is presented of a regional development model for valley economies in the mountain areas of Beijing, China. The nature and framework of the valley economy model are described and the development of the model, which is specific to the mountain areas of Beijing, is analyzed. Five different valley economy models applied in the Beijing mountain areas are compared. The major purpose of the valley economy model is to develop the regional economy, including the selection of appropriate industries, the allocation of industrial space, the establishment of supply chains and the integration of various industries. Pilot experiments using the valley economy model have been conducted in seven counties(districts) in Beijing: Pinggu, Huairou, Changping, Mentougou, and Fangshan districts, and Yanqing and Miyun counties. Five models for developing the Beijing mountain areas have been explored, including: creative cultural industries, characteristic industry clusters, the promotion of large tourist areas, natural scenic tourism and folk cultural tourism. Each model has its own unique features and potential to help in the regional development of mountain areas.

Comparisons between Movement Speed of Main Types of Dunes:A Case Study of Desert Areas in Hexi Region of Gansu Province

In desert areas in Hexi region,11 barchan dunes,6 chains of barchan dunes,6 pyramid dunes,6 parabolic dunes and 6 accumulated sand-belts were chosen to study their movement speed based on images obtained by Google Earth in various periods.The results show that among the dunes,the movement of the barchan dunes was the fastest,followed by the chains of barchan dunes,and only the tops of the pyramid dunes swayed,while the parabolic dunes and accumulated sand-belts hardly moved forward.The higher the barchan dunes(or the chains of barchan dunes) were,the slower the movement was.On the contrary,the higher the pyramid dunes were,the faster the swing was.There was a positive correlation between the movement speed of the barchan dunes and the average wind speed of sandstorms.

Numerical Simulation of the Regional Ocean Circulation in the Coastal Areas of China

The regional ocean circulation in the coastal areas of China (including a part of the western PacificOcean, the South China Sea and the Bay of Bengal et al.) is simulated by using the improved Princeton University ocean circulation model (POM). Compared with the modeling results obtained by the large-scaleocean general circulation model (OGCM), the basic ocean circulation features simulated by the regionalocean circulation model al-e in good agreement with that simulated by OGCM and some detailed characteristics such as the regional ocean circulation, sea temperature, salinity and flee sea surface height have alsobeen obtained which are in good accord with the observations. These results indicate that the regional oceancirculation model has good capability to produce the legional ocean circulation characteristics and it can beused to develop coupled legional ocean-atmospheric model systems.

Surface area processing in GIS for different mountain regions

Surface area is a fundamental parameter derived from terrain analysis in geographical information systems （GIS） for modeling the real world. Therefore, an evaluation of the techniques implemented by GIS models is important in order to obtain reliable area measurements. The study compares two raster-based methods with a TIN-based （triangulated irregular network） method for surface area approximation using a digital elevation model （DEM） with 25 m × 25 m resolution in six mountain regions of Shandong Province, China. Raster-based method I calculates surface-area grids from DEMs directly. Eight 3-dimensional triangles connecting the center point of each cell with the center points of the eight surrounding cells are generated and then the areas of the portions of each triangle that lay within the cell boundary are calculated and summed. Raster-based method Ⅱ produces the surface area of each cell directly from the pixel size and the slope value for the pixel. The results demonstrate that the surface areas calculated by rasterbased method I are equal to those of the TIN-based method. The results of raster-based method Ⅱ are the lowest but the difference in areas between the two raster-based methods decreases with the decrease in terrain complexity. Compared to the method with TINs, raster-based method II can do better because it has some advantages, such as neighborhood analysis, more consistent output and faster processing speed. The results also demonstrate that the difference between surface and horizontal areas should be considered if more than 30% of the area of a region has slopes steeper than 18.2 degrees.

Biomarker geochemistry of marine organic matter in the Hushan and Chaohu areas,Lower Yangtze region

Marine strata are widely exposed in the Hushan and Chaohu areas, Lower Yangtze region. As biomarker geochemistry of the strata has not been well documented, this paper deals with the biomarker composition of representative samples collected from the Silurian, Carboniferous and Triassic systems and their geological implications, thus providing clues to marine organic matter. On the basis of experimental results, it is shown that abundant biomarkers (e.g. n-alkanes, isoprenoids, terpanes and steranes) were detected. As organic matter in the strata is highly to over mature in general based on petrologic microobservation, some biomarkers (mainly n-alkanes) except terpanes and steranes cannot reflect the source, depositional environment and maturity of organic matter. Thus, primarily based on analyses of the terpanes and steranes, it is suggested that organic matter in the Silurian and Carboniferous strata is derived mainly from lower organisms, while higher plants are predominant in the Triassic organic matter. This further indicates that the depositional environment may have transformed from the marine to continental facies in the Late Triassic. These results provide new evidence for the study of regional depositional evolution, and have enriched the study of biological composition of organic matter. In addition, the biomarker geochemistry of organic matter at high to over maturation stage is addressed.

Gully Erosion Regionalization of Black Soil Area in Northeastern China

Gully erosion is the frequent and main form of soil erosion in the black soil area of the northeastern China, which is one of the most important commodity grain production bases in China. It is encroaching upon the fertile farmland there. Regionalization of gully erosion can reveal the spatial distribution and regularity of the development of gully erosion. Based on the eco-geographical regional background features of the black soil area, this study combined the regionalization with influencing factors of the development of gully erosion. GIS spatial analysis, geostatistical analysis, spatial statistics, reclassification, debris polygon processing and map algebra methods were employed. As a result, the black soil area was divided into 12 subregions. The field survey data on type, length, volume and other characteristics indicators of gully erosion were used to calibrate the results. Then the features of every subregion, such as where the gully erosion is, how serious it is, and why it happens and develops, were expounded. The result is not only an essential prerequisite for gully erosion surveys and monitoring, but also an important basis for gully erosion prevention.

Regional carrying capacity: case studies of Bohai Rim area

Carrying capacity research has been carried out for a long time. However, synthesized carrying capacity researches based on systematic views began only in the 1970s. There is even less work done in China. This paper tries to address both synthesized carrying capacity research and its utilization in China. State spaces method from the systematic science was borrowed to construct the conceptual model of regional carrying capacity. Based on the conceptual model and the surveys in the Bohai Rim area, we construct a representative indicators system for quantifying regional carrying capacity in the Bohai Rim. While employing system dynamic models we simulated the evolving trend of both the regional carrying states and regional carrying capacity from 1999 to 2015. The results proved the statement that Bohai Rim is overall over-capacity for a long time and will be over-capacity in the foreseeable future. Among all the restriction factors, water shortage and environmental pollution stand out to be the two primary obstacles for Bohai Rims sustainable development. Regional differentiation analysis further indicates that coastal areas of the Bohai Rim burden more than its overall level. However, Shandong province shows some good signs in addressing the regional carrying capacity issues. The research is successful in addressing the quantification of regional carrying capacity issues, but nonetheless it needs further refinery and more information.

Correlation of diseased region and area with neglect and other neuropsychological dysfunctions in patients with cerebral infarction

BACKGROUND: Previous studies reported that frontal-temporal-parietal-occipital pathological changes and diseased range in the right cerebral hemisphere were closely correlated with neglect. But studies on the correlation of neglect with diseased region and area in patients who suffer from initial attack of single focus of cerebral infarction (CI) in left and right cerebral hemispheres are few. OBJECTIVE: To observe the status of neglect in patients who suffer from single focus of CI in cerebral hemisphere, and analyze the correlation of neglect with diseased region and area of CI. DESIGN: Case analysis. SETTING: Treatment Center for Cardiocerebrovascular Disease, Second Hospital of Xiamen city; Department of Neurology, First Hospital Affiliated to Baotou Medical College. PARTICIPANTS: All the CI patients hospitalized in the Department of Neurology, First Hospital Affiliated to Baotou Medical College from June 1998 to May 2001 were retrieved. Inclusive criteria: ① Patients who suffered from initial attack of CI, which was confirmed by skull CT or MRI within 24 hours after onset and presented single focus in cerebral hemisphere. ② be conscious and could cooperate in the examination. ③ did not receive formal education, but could do accounts and some simple writing and reading. ④Patients with homonymous hemianopia were excluded through the examination of perimeter. ⑤ Informed consents were obtained from all the patients. Among 67 patients who met the inclusive criteria, 33 suffered from CI in the left cerebral hemisphere and 34 in the right cerebral hemisphere. METHODS: ① Patients received neglect supplement examination and Chinese aphasia examination within 2.5 to 3 months after the attack of CI . The diagnostic criteria of neglect in the tests of line cancellation, line bisection and copying the figures were as follows: In the line cancellation test based on the method of Albert, patients who could not cancel one or more lines were regarded as abnormal. In the line bisection test based on the method of Peter, patients who left deviated 1.16% or right deviated 2.51% were regarded as abnormal. In the test of copying the figures, round-shape, square, cruciform and other shapes were asked to be copied, defect appeared in the figure was regarded as abnormal. The diagnostic criteria of aphasia were according to the diagnostic method of Chinese aphasia examination and type identification flow-sheet of aphasia. Infarct area was calculated based on Palisino formula: infarct area=π/6×the longest diameter of infarct area×the widest diameter of infarct area×the number of CT positive layer. ② Chi-square test was used for comparing the difference of measurement data. MAIN OUTCOME MEASURES: Diseased region and area of CI and their correlations with neglect. RESULTS: Sixty-seven patients were involved in result analysis. ① The correlation of the occurrence of neglect with the diseased regions of CI: Neglect was not found in 33 patients with CI in left cerebral hemisphere, but was found in 7 of 34 patients with CI in right cerebral hemisphere. The diseased regions involved right temporoparietal region, temporal-parietal-occipital region, frontal-temporal-parietal region, frontal-temporal-parietal-occipital region, temporoparietal basal nucleus, basal nucleus and dorsal caudate putamen. ②The correlation of the occurrence of neglect with diseased area: infarct area ≤ 30 cm3 was found in 2 patients with neglect (12.5%), infarct area at 31 to 60 cm3 in 1 patient with neglect (14.3%),infarct area ≥ 61 cm3 in 4 patients with neglect (36.4%). There was no significant difference in infarct area among groups (P > 0.05). CONCLUSION: ① Right cerebral hemisphere takes advantage in spatial attention. ② Neglect is more possibly caused by the combined pathological changes in temporal and parietal lobe. Temporal and parietal lobes may not cause neglect independently, but the occurrence of neglect is not directly correlated with infarct area.
